The Washington Department of Ecology proposes a modification to the Waste Treatment and Immobilization Plant (WTP) Permit. The permittees are the U.S. Department of Energy Office of River Protection and Bechtel National, Inc.

What Changes are Being Proposed?

The proposed changes address the Environmental Risk Assessment Work Plan for the WTP permit. In support of the risk assessment, the permittees have submitted the final Environmental Risk Assessment Work Plan and associated supplemental documentation to Ecology for inclusion in the permit. This work plan and associated documentation will replace documents that are currently in the WTP permit.
